4.3.3 Channel body 17 (Djupskaret)Channel body 17 is located only a few hundred meters south of channel body 4. It has amaximum thickness of around 5 meters and is approximately 150 meters wide. It is possibleto see a clear transition between light coloured layers dipping towards the north (Figure 4.35)and darker sediments (marked with red in Figure 4.35E), which seem to erode into the lightercoloured sediments. On the southern side of the light coloured layers, one can still see dippinglayers, but with a darker colour (Figure 4.35).By extrapolating the Hopen member from Johan Hjortfjellet further south, one can estimatethat Channel body 17 is situated about 135 meters below Hopen member.(1) DiscussionA log was taken through Djupskaret on the 2011 expedition to Hopen (Figure 4.35A). Thislog is taken a bit north of Channel body 17, and hence they did not log the actual channelbody. The channel body is situated towards the top of this gully, hence the upper most part ofthe log will be the stratigraphical interval of Channel body 17. In this part of the log (Figure4.35) the sediments contain ripple lamination and root structures, as well as what might bepaleosols. Paleosols are defined as a floodplain marker horizon by Miall (2006), whichconfirms that it is deposited on the delta plain. This leads to the assumption that this channelbody is deposited on the delta plain and might be a fluvial dominated distributary channel.When examining the photo of this channel body, one can see that the darker colouredsediments (red in Figure 4.35E) are most likely a mud-plug filling in the channel where thechannel ultimately has been abandoned. The more light coloured part is than perhaps point bardeposits, as described in subsection 4.3.1.87
